摘要：
The sonic or ultrasonic transducer includes a circular piezo-ceramic disk capable of generating radial oscillations, and a metal ring, which embraces in tight close fitting relationship the circumferential surface area of the disk to form a radial oscillator in conjunction with the disk. The sonic or ultrasonic transducer formed in this manner has an emission surface corresponding to the entire surface area of the piezo-ceramic disk and metal ring, and displays a radial resonant frequency which is lower than that of the piezo-ceramic disk.
